摘要： A bias circuit that supplies bias voltage or bias current to one end of a transmission line includes an inductor that prohibits a high frequency component of a baseband signal transmitted on the transmission line and passes a frequency component near direct current of the baseband signal, and an impedance-decrease prevention element that prevents impedance from decreasing, when viewed from the transmission line, that is produced due to a resonance between a parasitic capacitance generated due to the inductor and an inductance of the inductor.

摘要： Because the phase comparison of the light signal data row and the light clock signal, and the coding of the light signal by the light signal, are simultaneously conducted, the influence of the phase variation in the signal path is not affected in principle, and the optimum phase condition is automatically established/maintained, and thereby, the present invention operates as an all-light type light receiver by which the light data and light clock are reproduced. Further, because the electric signal used herein exists in the range from the DC to the frequency of the difference between the light signal data row and the light clock signal, problems peculiar to the high speed electric signal can be avoided.

摘要： In a network computer system wherein the type of keyboard at a managing terminal is different from the type of keyboard at a managed terminal, keyboard scan code data from the keyboard at the managing terminal is first converted to virtual scan code data. Next, the virtual scan code data is converted to keyboard scan code data that is compatible with the keyboard at the managed terminal. This conversion, which uses two conversion tables that are selected from a plurality of conversion tables by detecting the different types of keyboards at the managing and managed terminals, permits the keyboard at the managing terminal to be of a different type than that at the managed terminal.
